[Q] My Super amoled is not that super anymore? - Galaxy S I9000 General

When i bought my galaxy i was very impressed from its colorfull screen and especially it's black color.
Now after 1.5 years i think that my screen isn't that cool.As for the black colors when i see an image with different shades there are some strange colors like grey or "pixeled" colors.I don't know if you understand what is my problem but i want to fix it somehow.I tried voodoo color but the same thing happenes.Only if i reduse the
colors from voodoo control the screen gets better but then i have no brightness...Any help or settings about this?I have used many roms including gb(cm7) and ics(simply ,icssgs,and aokp) and many kernels and i have always the same problem.

Screen burn-in . Happens if your brightness is too high, or a pixel shows the same color for a longer time. Normal after 1.5 years.

Not sure, my screen had a problem displaying greys until I started using voodoo color and set it up correctly.
Try these voodoo color settings, it's bright even on low brightness settings.

If it still has the same problem you might have to take your phone to Samsung for repairs. Does it still have warranty?

My waranty is over.As for the burn in thing i ve tried the phone test with the code *#*#0*#*#* and nothing happens..dunno why maybe this code doesn't run on ics can someone tell me if it works at his phone?

I don't think you have burn in from what you said in the op. Install a dead pixel test app from the play store if you want to look for burn in anyway.

Share your CM7 Voodoo Color settings

There's a thread on this in the Nexus S forum, but I figured we could start one here for the locals.
Thanks to Tk-Glitch and times_infinity, we now have the beauty that is Voodoo Color available for CM7. Please share and discuss your voodoo color settings. Of course, everyone's experience will vary. This is just what works for your phone.
Here's mine:

It would be awesome if somebody that has a display calabrating device stick it on the phone and give use some "professional" numbers to start off at. This is done often in the HDTV world.

The only quirk with these settings is having to leave minimum brightness at the default 20%, no biggie.

Yeah its a good start, they are similar to what I ended up with after an hour of messing around with the phone. The thing that sticks out to me is the screen clarity definitely suffered. If you get a picture that has tiny details like a black leather wallpaper that shows grain, there is a noticeable difference from stock to the above posted settings in shadow detail and image clarity. I'll keep messing around with it more and post later on.

Nope. This setting will be safe.
Also,
And just as an update, glitch's new kernel fixes this issue (beta tested atm); so you will be able to use any setting you want without the screen freaking out once he releases it.
Anyone have any better settings for our device? The nexus s ones look pretty good. Anyone do a pro calibration yet for the fascinate?

Bumping this to see if we can get anymore setups
I'll post my setup just in case anyone else finds it useful. I found that some of the settings posted were somewhat red/green when the screen was really dim (my dim setting is at 10), so I blued it up a bit. Things may not be all that different from stock, I haven't really compared.

EDIT: When looking at my gmail inbox (namely, unread messages), I still found the gray to be too red. If you agree, I've toned the red setting in SRGB to 21168...
Cleanest colors for me were as follows:
RGB Mulipliers:
Red=4294967290
Green=3354165120
Blue=4294967290
Gamma Offsets:

All the others I tried were just too red, green, or dark. These are perfect for me, try it out yourself!
--Changed my settings a couple days later..see this post.
Spent some time and found these to be the best settings for me.

Well, tried all the other listed here...liking yours the best so far..wish the app allowed you to TYPE in the values as well as the sliders...o well..
Anyone have the equivalent stock values for this(CM7 stock kernel)...I flashed the glitch kernel and was very put off by the ugly warm color scheme....what was wrong with stock colors any way...IMO they should have some Presets, like Stock, Cool Warm, Standard...kinda like they do for desktop monitors..

It will be fixed in the next glitch update. I'm about to post my color settings which have great vibrance in all brightnesses and color ranges, white whites and black blacks. I have tried just about every recommended setting and nothing has looked quite right until I spent some time making my own.

Not a fan of Voodoo Color

I just tried the latest Samurai kernel with Voodoo Color and I am not a fan. I know a lot of people love it but personally I don't. At first boot your phone is dim. Then you have to download an app to set the colors. I tried several people's suggestions and didn't like any of them. So there is constant fiddling to get the colors the way I would like. Plus I had to turn my display up to about 35% when normally use about 15%. That has to eat up more battery, as well as constant adjusting. Then between the kernel and Voodoo app I am down 30 MB of RAM then what I normally have. I know for gaming it is probably the shizzle but for just a phone and browsing, not needed.
I flashed back to Samurai 2.08 and phone looks great still, lower screen brightness and actually is faster. Not sure if that is the kernel or lack of voodoo color.
Just had to get that out. I am sure this will open up a pros and cons discussion of voodoo color. I guess this would be a first edition of Kenny's Blog...LOL.

I dont really care much for it either. Whenever I start up a rom with a fresh voodoo kernel, the screen is piss yellow. I have tried a few different setting suggestions, but the screen is always way too blue. My friends drewl over this super AMOLED screen without doing anything to it.... i kind of agree with them.
Meh I tried it, thought itd be sweet, but not really lol. Using chainfire is better (Nightmode). Voodoo color is fun to mess with, for a few minutes XD
Sent from my SPH-D700 using xda premium
I agree. Didn't see significant benefit to having it either! (On the Epic) I think it can make a huge difference on other devices though, from images I've seen. Not to knock the Voodoo team as their work is awesome.
I AM a fan of CM7's RenderFX (and widgets) that can make the screen go all green or red or low cal night mode (and more) - each with a single toggle - is pretty damn sweet!
My feeling on this is if you need a program to custom tweak the nominal display colors as if its a high end digital cinema: maybe you got the wrong phone.

I like it, it makes my blacks blacker, and my whites whiter... as for the resources it takes, that I do agree with, not that it takes a lot, but 2.0.8 was a little quicker for me. I keep my phone at about 5 - 10 percent brightness all day. I think it looks nice though, personally I feel it is better then stock. And if you are getting the yellow stuff on boot, or on dim, probably have the wrong settings.

@kennyglass123
I've been tempted to post the same thing, but I assumed I must be doing something wrong because everyone else seems to love Voodoo Color. I tried every combination of settings that have been posted (including those above), and though they may add some punchiness, the colors always seem to be very unbalanced/inaccurate (either too blue, or too yellow, or too something else I can't put my finger on). I also tried dozens of my own combinations, just can't get it set to anything that doesn't end up bugging me after a while. Oh well, I'm going to follow your lead and flash back to 2.08 for a while and see if I miss Voodoo.
I like my phone really dark, and that might not be for everyone
Some of this may be due to inevitable inconsistencies in these screens of ours from their factory days. But I find VC to be preferable even at defaults. Colors seem much truer and the nasty bluish tint over much of the screen is lessened.
I love it. Not sure what it's doing for everyone else that doesn't seem to be causing a problem here.
Here are my settings, took me a bit to get my screen to where it looks best for me:

Wow.. are you reading my mind? I flashed it and ran for a few days. Even a very non-technical co-worker saw my phone and asked if my screen was going out since the colors looked weird. She always commented on how beautiful the screen looked.
Had to crank up my screen brightness turning off auto-brightness as well which is killing my battery.
Soo..what's a stable Samurai to go to? I'm not interested in voodoo, oc/vu, just plain ole I want my daily driver to work.
2.08 is the recommended stable replacement according to Earthbound.

I wouldn't call it a problem, just like I said, not a fan. I tried several suggested settings and no matter what on some screen something always seemed off. That and having to crank the display brightness up is just not for me. I am real happy with the beauty of the stock colors. I see the potential for the voodoo color but it would take too much work and adjusting until I would be happy with it.

Did you try the other color profile?
im running Marcus's rom, which comes with sam 2.06.
I tried flashing the new sammy colonel last night, and aside from the fact that the colors looked piss yellow, it was really laggy.. to the point were i reflashed the rom to get 2.06 back.. didnt really see that coming
Also, Im not really sure what everyones talking about with the "blueish" tint of the stock colors. I held my epic up to my GFs Moto Atrix, expecting to marvel at how much better my samsung screen looked, only to find that (even on the stock, non-VC colors) it looked piss yellow compared to her moto.
So, aside from not wanting to have to eff with the color settings, the main kernal right now that has it, apparently, hates my phone anyways

Ok , I have two epic s, one is refurbished so I'm sure it has some mileage on it.
side by side the differences are noticable. Exactly the same except voodoo has brighter, blue tinted whites... A little better darks. I will post pics today.
the voodoo epic does look pretty damn nice, but in the end, its all about personal preference.

Only on 1st boot and look. Then I saw everyone using the 2nd profile and tried all the settings I can find. There was always something off, one was too blue, one was too warm, one was too brown, and all were too dark requiring at least doubling my normal brightness setting which uses up more battery.
I would spend time tweaking my TV a little but don't want to keep doing it for the phone. It is awesome that it is better than sliced bread for a lot of users but just not for me.

[SETTINGS & QUESTION] CM Color tuning, post question and settings here

Ok, i started this thread to discuss about new CM9 feature: the color tuning

hi there...before i start fiddling with it..can u help me understand what each slider do?
Also..right now the CM colors are perfect but there is a lot of noise in darker pictures how can i correct it without making the overall picture yellowish?
thanks!

First slider's series concern rgb adjustement, the second change the gamma of each color
I'm trying to understand how it works properly
With these adjustment you can mix red,green and blu and try to have best looking possible color
If you set all color t same setting would be few useless, we must try differents level to have acceptable black and white, which are the extreme opposite colors
Maybe someone can help faster than me
As I wrote in the CM9 General thread, your settings look amazing erto90.
I tried messing around myself but I don't have the eye for this stuff.

Ok thanks, but i opened the thread to share our settings
I've reached my settings after 15m of trying but i think we can do better!
So, guys, share best settings you can!
So messing around again with this, I just put gamma to 20 on all colors, using the color settings in OP, and I am really liking it.

My settings for yellow tinted screens such as mine.
0.680
0.573
0.884
-16
-20
-17
That's made to avoid the green bug at minimum darkness and to try to keep acceptable dark greys.
Sure it's still quite saturated but anything with more gamma turn the grey too bright...
Though I have to say it's better than Voodoo hack, perhaps because the MDNIE are disabled (they lighten the greys and turn them red on Samsung roms).

It's a kind of filter that boosts particular colours, quite like digital vibrance on your PC video card.
I don't like this, it gives more banding and tint in the dark greys.

We all know that some of the color looks washed when we watch in a diff angle , also the head on looks sometimes may not look great since BE2 is not applied all time .
not sure if this works as I dont have a rooted phone ( dont plan to root till 4.2 ) can anyone test this on their rooted phone and post results and reviews please?

this appears to work very well with the Nexus4 hope should work on the XZ too
awaiting positive results
does this work?? any conformation..

This app is incompatible with your SingTel Sony C6603. Sadly.

Try screen adjuster. Does not require root.
Tried it. It doesn't work. Gives an error everyone you try run it

It won't work more than likely because it is based on the Nexus 4 hardware.

No error on mine(stock rom). However not really good at adjusting the screen color.
Adjusted as per image. Picture shown the with and without.

If you just want to deal with the view angle problem, set the system brightness higher (80% or higher), and set the brightness of the screen adjuster to 50%~70%, nothing else. Then the view angle will be amazing, but you will also find very little blue tint when displaying white color

done, thank you. The angle view does seems to be better.

Wow, call it placebo or whatnot, but it seems as though it helps to some extent! (maybe it's just me) O_O!

Gpad screen gamma is too low

Some of you may have noticed it's difficult to watch dark scenes in movies on the gpad. I think the problem is the gamma calibration, you can see it clearly on the pictures I took.

On the top you can see my nexus 7 2013, you can differentiate all the shades of grey from 1% white to 100%.
On the gpad, everything is solid black from 1% to 12% of white.
You can find the original image here : http://imageshack.us/f/594/6291.png/
How low can you go, on your gpad, before the grey melts with the black ?
Do you know an app to apply gamma correction ?
Here you can see the same picture on the N7 and the gpad. You can't even distinguish the guy's ear on the g pad.

I see the difference, and I knew it was there already also.. I'm sorry, but apparently gamma is not something that is doable. - I was looking to link you the app from market called "Screen Adjuster", however you want to look at this description, especially the last sentence. ;/
- dimming the screen 15-100% (below minimum system brightness)
- screen color and a contrast adjustment
- system brightness 0-100% adjustment
- functional widget (on/off, system brightness, settings)
- autorun option
Some phones have a color tint screen. This app have a possibility to try to improve colors on this kind of the screen by setting an additional factor RGB.*
The range of the dimmer is from 15% to 100% (it allows to dim the screen below a min system brightness value). Make a relief for your eyes during a nightly reading.
Furthermore, you can change fast the system brightness too.
The additional contrast factor can try to make the reading or a picture viewing more comfortable on some screens.*
The widget provides fast on/off service with a shortcuts to the Adjuster settings and the system brightness settings.
The application has the autorun option which works with the dimmer set above 22% (for the safety).
Note
A gamma adjustment is not possible to do.
You can of course try and download the app anyways and see if contrast or brightness will do anything for ya.
- In case you do download the app, remember that setting contrast low will result in problems with installing apps, as in you cannot hit Install, only cancel. To avoid this, open up Screen Adjuster and turn it off, install the app and turn it back on afterwards. It's something about lowering the settings to lower than what is "intended", I don't quite understand it and I find it rather odd. But it let's you install apps.. So I guess hooray.
That's all I got.

Thank you for your response, but I'm already using screen adjuster. I set the contrast at -25 and it helps a lot to see dark details.
Unfortunately, it has two side effects :
- it brightens the dark shades of grey, but also the black levels.
- I noticed that the contrast setting also affects the white making it look like light grey.
So the contrast setting in screen adjuster doesn't affects only the dark tones like it would on a monitor or a tv, it affects the contrast ratio.
I've found apps to make gamma adustment but it only works on some devices with custom kernel.

Yea, I was about to say that gamma can be done but only on custom kernels. Lot of Nexus 5 stuff on the market. Apparently it's Google who locked the gamma settings completely down but only in 4.4.2. I guess it may work on stock LG Kernel since it's only 4.2.2? I'm afraid we'll have to wait for some kernel support for other roms. That would be awesome. I really hope for some Franco-kernel-glory on this device.
That's what I thought, we need to wait for custom kernels...I hope it will come soon, because it's so frustrating to have such a good screen with bad calibration !
People tends to complain too much about the warm white balance but the gamma calibration is far more concerning.

I hope @dalingrin can cook something up to address both. He said he was going to work on something.

Yes it would be great if he did , though he's done so much for us already.

I see someone had developed a nude kernel for our devices. I welder off they can add support for gamma adjustment

Hi there Young Bobbie, I am new to posting on XDA so I couldn't post this in your kernel developer page. This is my first post on any forum page ever. First off, thank you very much for your hard work to make this kernel happen to correct gamma on the v500. I have been sitting on the fence whether to get the gpad, and if i would get the v500 or the v510. Was leaning toward the v510 because of Sleekmason's wonderful kernel work, but it's exciting that we have now have the same options available for the v500. I noticed this was working fully with the Malladus ROM. My question to you was whether or not this worked with stock LG ROM as well? Thank you again YoungBobbie and Sleekmason for your time and creations.
Sorry, just answered my own question. Guess it helps to read the very first line of the page (making fun of myself now ;-P) Thank you again YoungBobbie and sleekmason!!!

Gald to have helped would you be willing to try the kernel for the stock LG ROM?
Please take a look at the images below and compare
The tablet on the right is running my kernel and the left stock
You can see the differences on the first image as the deepness of the blacks
and on the second the highlights on the white
I just about to get this tablet, then i so this problem... ?
